13.1 Commands
CM/CM?
Selects scaling constants simultaneous
setting command group or individual
setting command group for command
data which come after this command/
inquires about the current setting.
Syntax
CM m <terminator>
“m” indicates command group used.
m= 0: WT210/230 command/output
format group (scaling
constant simultaneous
setting command group)
1: command/output format
group by element (scaling
constant individual
setting command group)
Query
CM? <terminator>
Example CM1
Description • Parameter error 12 will occur if “m” is set to
an illegal value.
• The output format of the WT210 is the same
for m=0 or 1.
DA/DA?
Syntax
Sets the function for display A/inquires
about the current setting.
DA m <terminator>
“m” indicates one of the following
functions.
• in case of normal measurement
m= 1: voltage (V)
2: current (A)
3: power (W)
4: reactive power (var)
5: apparent power (VA)
15: Elapsed integration time
(TIME)
• in case of harmonic measurement
m= 1: Each relative harmonic
content of 1st to 50 (or
30) th order of voltage
(V)
2: Each relative harmonic
content of 1st to 50 (or
30) th order of current
(A)
3: Each relative harmonic
content of 1st to 50 (or
30) th order of active
power (W)
28: harmonic measurement order
(order)
Query
DA? <terminator>
Example DA1
Description Parameter error 12 will occur if “m” is set to an
illegal value.
13-2

of each active power
component (W %)
22: Phase angle between each
voltage of the 2nd to 50
(or 30) th order and the
fundamental (1st order)
voltage.
23: Phase angle between each
current of the 2nd to 50
(or 30) th order and the
